Why is it so few people actually do full squats?
I see plenty of people at the gym doing quarter squats and some half squats but very rarely do I see full squats. I do realize that full squats require more flexibility and it's not as easy to use heavy weight but what happened to full range of motion? Furthermore what's happened to squat racks? Some gyms I have visited recently only have one.
Now I will say that I do know about the going parallel paranoia, but mechanically speaking you put far more pressure on the knees at parallel than but going all the way into the hole.

I was showing someone how to squat a few months ago and a friend who is studying to be a high school phys ed teacher was watching. He was shocked that I would suggest going lower than a 90 degree bend in the knee.
